ABSTRACT:
An average-temperature compensated field device comprises a field module, a temperature-averaging sensor, a microprocessor, and an interface. The field module is configured to characterize a process parameter. The temperature-averaging sensor is configured to generate a compensation signal characterizing an extended region of the field device. The microprocessor is configured to compensate a process signal as a function of the compensation signal. The interface is configured to communicate the process signal via a field device communication protocol.
